How much should this gap actually matter?
A 19% spread (roughly $1,100) is significant enough to plan around, but not fixed — off-peak timing and sharper bidding in Chicago typically recover some of it.

Furnace replacement by home size: Champaign vs Chicago
Furnace cost scales with the heating capacity (BTU) your home needs — roughly 40–45 BTU per square foot in a mixed climate. Larger homes need a bigger unit and more ductwork.
| Size | Champaign | Chicago |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $3,050–$5,500 | $3,650–$6,600 |
| 1,500 sq ft (≈68,000 BTU) | $3,550–$6,350 | $4,250–$7,600 |
| 2,000 sq ft (≈90,000 BTU) | $4,100–$7,350 | $4,900–$8,800 |
| 2,500 sq ft (≈110,000 BTU) | $4,700–$8,350 | $5,600–$10,050 |
| 3,000 sq ft (≈130,000 BTU) | $5,300–$9,400 | $6,350–$11,250 |
| 3,500+ sq ft (≈150,000 BTU) | $5,900–$10,400 | $7,100–$12,500 |

What hvac pros earn in each metro
Roughly 60% of what you pay for furnace replacement is labor, which is why local wages explain most of the price gap. The numbers below are actual metro wages for skilled installers, sourced from BLS OEWS — not guesses.

Cheapest time for furnace replacement in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
How much should you really budget for HVAC in 2026?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
The longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.

Should I choose where to live based on furnace replacement cost?
